Meteor Crater
Scientists have identified the faint outline of part of an ancient meteor crater on the coast of Mexico. The rest of the approximately circular crater lies underwater. The crater’s diameter is about 170 kilometers. Approximate the distance around the crater to the nearest kilometer.
Norman Window
A Norman window from Congress Hall in Philadelphia consists of a rectangle and a half circle, as shown. Find the area of the window to the nearest square foot.
